Performance Analysis of Hydrological and Data Based models in Estimation of Suspended Sediment Rate [PDF]
محیط زیست و مهندسی آب, 2022 Data driven models are proposed as an alternative to hydrological methods in sediment estimation calculations. The aim of this study was to compare the performance and accuracy of hydrological and data-based methods in estimating the amount of suspended ...

Suspended sediments mediate microplastic sedimentation in unidirectional flows
Science of The Total Environment, 2023 Microplastic particles (MP) are an emerging contaminant threatening many aquatic systems. Because of the sharp increase in plastic manufacture, the concentration of MP in natural ecosystems has grown dramatically. While it is known that when MP enter aquatic ecosystems they are transported and dispersed via different mechanisms (currents, waves ...

What is suspended sediment? [PDF]
Earth Surface Processes and Landforms, 2015 AbstractSuspended sediment is conventionally regarded as that sediment transported by a fluid that it is fine enough for turbulent eddies to outweigh settling of the particles through the fluid. Early work in the fluvial field attributed suspension to turbulence, and led to the notion of a critical threshold for maintaining sediment in suspension ...

The sedimentology and dynamics of mega-dunes, Jamuna river, Bangladesh [PDF]
, 1998 This thesis quantifies the occurrence, morphology and flow dynamics of dune bcdforms in the main rivers of Bangladesh: the Jamuna, Meghna and Ganges. Field work was conducted as part of the River Survey Project (Bangladesh Flood Action Plan 24) between ...

Estimating Suspended Sediment Concentration by a Neaural Differential Evolution and Comparision it with ANFIS and RBF Models (Case study : Givi Chay River ) [PDF]
جغرافیا و توسعه, 2015 In this study, neural differential evolution (NDE) models were used to estimate suspended sediment concentration. NDE models are improved by combining two methods, neural networks and differential evolution.

Suspended sediment modeling by SVM and wavelet [PDF]
Journal of the Croatian Association of Civil Engineers, 2014 Present-day advances in artificial intelligence, as a forecaster for hydrological events, have led to numerous changes in forecasting. The wavelet support vector machine (WSWM) model is achieved by conjunction of the wavelet analysis and the support vector machine (SVM).
